Japanese Inflation- Part 2 Liquidity Crisis In The Making

 | May 04, 2022 05:46AM ET

We ended Liquidity Crisis in the Marking- Japan’s Role in Financial Stability- Part 1 with the following quote regarding inflation from BOJ Governor Haruhiko Kuroda:

“The BoJ should persistently continue with the current aggressive money easing toward achieving the price stability target of 2% in a stable manner.”

While many central bankers are anxiously waging war against inflation, the Japanese are egging it on. Over the last few weeks, the BOJ has offered to buy as many 10-year notes at 0.25% as the market will offer them.

In central bank parlance, we call that unlimited QE. While the BOJ caps bond yields with “aggressive” QE, they are doing so at the expense of the yen.

In Part 1, we discussed how Japanese citizens and pension plans invested abroad to earn higher yields. They were not the only ones taking advantage of the difference in interest rates between Japan and many other countries.

Hedge funds and institutional investors worldwide were also making the most of the situation by borrowing yen cheaply in Japan, converting the yen to another currency, and investing the funds at much higher rates. Such a trade is called a carry trade.

To understand the allure of the carry trade, let’s consider a popular carry trade that many of you are actively engaged in.

Buying a house with a mortgage is a type of carry trade. If you purchase a home for $500,000 with a $400,000 mortgage and $100,000 in cash/equity, you are leveraged at a rate of 5:1. Any change in the home price affects your return on the investment by a factor of five. For instance, a 10% increase in the price ($50k) results in a 50% gain on your equity ($50k/$100k).

Leverage can be much greater than 5:1 in financial market carry trades, thus resulting in more significant gains and losses than in our example.

Unlike mortgage payments and house values denominated in dollars, the yen carry trade introduces currency risk. If you borrow in yen and it appreciates, you pay back the loan with more expensive yen. Therefore, appreciation of the yen eats into profits and discourages the yen carry trade.

For example, you go to a Japanese bank and put down $100,000 in assets to borrow 1,000,000 yen for one year at 0%. You convert the yen to dollars and buy a one-year U.S. Treasury note at 3%.

Assuming the yen’s value doesn’t change versus the dollar, the return will be 30% (3% * 10x leverage). If the yen appreciates by 1% over the year, and you did not hedge the currency risk, the return falls to 20%. 5% appreciation of the yen results in a 20% loss.

As you might surmise, yen carry trades are very sensitive to yen price movement. Understanding this, the BOJ has acted numerous times to arrest the yen’s appreciation. We share the following from the book The Rise of Carry:

“Over a period of just seven months up to March 2004, the BOJ/MOF accumulated well over US$250 billion in foreign reserves in the attempt to prevent the yen from appreciating. At the end of this period, the yen dollar exchange rate was basically flatlining as the BOJ stood in the market and absorbed all the dollars that yen purchasers wished to sell.”

At that time and many other times, the BOJ bought dollars and sold yen to keep the exchange rate stable. By minimizing currency risk, the yen carry trade retained its attractiveness to foreign investors.

The size of the yen carry trade has declined in recent years, as shown below. Even at 100 trillion yen, carry trade investors control approximately $80 billion worth of assets worldwide.
